The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, if terms indicating orientation such as "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc., are used, they indicate orientation or positional relationship based on that shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 to 21, the present invention provides an air sterilizer, which includes a box body 1, wherein the box body 1 has an air inlet 2 and an air outlet 3, a blower 4, an air filtering mechanism 5, a photocatalyst and a plurality of ultraviolet sterilizing mechanisms 6 are arranged in the box body 1, at least one ultraviolet sterilizing mechanism 6 is arranged on a side wall of the box body 1, the ultraviolet sterilizing mechanism 6 on the side wall of the box body 1 includes an ultraviolet lamp tube 7 and a driving device 8, and the driving device 8 can adjust an irradiation range of the ultraviolet lamp tube 7 to at least implement the following two functions: firstly, only the inside of the box body 1 is irradiated; secondly, only irradiating the outside of the box body 1 or irradiating the inside and the outside of the box body 1 simultaneously; when the ultraviolet lamp tube 7 irradiates the inside of the box body 1, the photocatalyst is positioned in the irradiation range of the ultraviolet lamp tube 7.
It can be understood that the irradiation range of the ultraviolet lamp tube of the ultraviolet sterilization mechanism arranged on the side wall of the box body can be adjusted under the action of the driving device, and can be adjusted to irradiate the outside of the box, the inside of the box and the inside and the outside of the box simultaneously according to requirements, wherein the latter two can be realized by only one or both of the two. Under the condition that the ultraviolet sterilization mechanism can effectively enable light to be damaged and excited by irradiation when irradiating the inside of the box on the side wall, a built-in ultraviolet lamp specially used for exciting photocatalyst can not be arranged in the box body, the structure is simple, certainly, in order to have more choices and realize more and better functions, the built-in ultraviolet lamp can be also arranged in the box body, for example, when the air filtering mechanism is a metal air filter cylinder coated with photocatalyst coatings such as titanium dioxide, the inner wall and the outer wall of the metal air filter cylinder can be irradiated by the built-in ultraviolet lamp from the inside of the cylinder, the outer wall of the metal air filter cylinder is irradiated by the ultraviolet lamp tube of the ultraviolet sterilization mechanism from the outside, the inner wall and the outer wall are irradiated simultaneously, and the effect that the photocatalyst is excited to catalyze and oxidize harmful substances in the air is better.

It should be noted that the driving device can stay at a plurality of angles and be positioned when driving the lamp holder to rotate, and is not limited to the two angles, and the ultraviolet lamp tube does not necessarily need to be powered off in the process that the driving device drives the lamp holder to rotate, and can synchronously rotate under the condition of power on, so as to achieve the large-range searchlight type back-and-forth swinging irradiation sterilization. When the shading plate completely blocks the external irradiation opening, the ultraviolet lamp stays at the angle, the ultraviolet lamp can perform irradiation sterilization in the box or perform air overflowing sterilization by matching with a photocatalyst (photocatalyst) in the box, and at the moment, due to the blocking effect of the shading plate, the ultraviolet ray cannot irradiate the area outside the box, so that people moving under the environment outside the box are not injured. In fig. 7, the front side wall of the housing 9 is provided with an outside irradiation opening 11, and the front and rear side walls of the housing 9 may be made of an ultraviolet-transmitting material (quartz glass or the like), and both the rear side wall and the front side wall may be absent.

The ultraviolet sterilization mechanism for realizing the adjustment of the irradiation range of the ultraviolet lamp tube 7 comprises a lamp bracket and a shell structure, and is realized by rotating the ultraviolet lamp tube relative to the shell and the box body. Specifically, in an embodiment of the present invention, the ultraviolet sterilization mechanism 6 on the sidewall of the box 1 includes a fixed frame and a rotating lampshade, the ultraviolet lamp 7 is fixedly connected to the sidewall of the box 1 through the fixed frame, the rotating lampshade is covered outside the ultraviolet lamp 7 and is connected to the output end of the driving device 8, the rotating lampshade has at least one light-transmitting window, the driving device 8 drives the rotating lampshade to rotate and adjust to one angle, the light-transmitting window aligns inside the box 1, and when the rotating lampshade rotates and adjusts to another angle, the light-transmitting window aligns outside the box 1. It can be understood that when the lampshade is provided with a pair of light-transmitting windows which are oppositely arranged, the external and the internal of the box body can be irradiated simultaneously, and at the moment, one of the two light-transmitting windows is aligned with the internal of the box body, and the other light-transmitting window is aligned with the external of the box body. In addition, in order to realize the irradiation only to the inside of the box, besides the two light-transmitting windows which are oppositely arranged, the rotary lamp shade can be also provided with an internal irradiation light-transmitting window, when the rotary lamp shade rotates to a proper angle, the internal irradiation light-transmitting window is aligned with the inside of the box body, and the other side walls of the lamp shade just completely block the light irradiated to the outside of the box by the ultraviolet lamp tube. In addition to the ultraviolet lamp tube irradiation range adjustment by the integral rotation mode of the lampshade, the irradiation range adjustment of the lampshade can be realized by a mode similar to opening and closing a door.

It can be understood that the above-mentioned various disinfection modes can be automatically selected according to a preset program, for example, if the air sterilizer is applied to a subway station platform or a classroom or other specific places, and no personnel are active at a specific time interval at night, it can be set that a relatively energy-saving external irradiation disinfection mode or a hybrid disinfection mode is started at the specific time interval, and an internal overflowing disinfection mode with better safety is started due to frequent and continuous activities of personnel at other time intervals. Of course, when the external irradiation disinfection mode or the hybrid disinfection mode is started, the human body induction switch continuously or at least continuously monitors whether there is human activity in the external environment at intervals of a specific time (for example, 2-5 min), and once there is human activity, the external irradiation disinfection mode or the hybrid disinfection mode is stopped and the internal overflowing disinfection mode is switched. In addition, when the internal overflowing disinfection mode is continuously carried out, the ultraviolet lamp tube and the built-in ultraviolet lamp tube can be selected to be only opened or simultaneously opened, whether the unmanned activity is carried out for a long time (such as 30min upwards) can be judged according to the continuous monitoring condition of the external environment, and if the unmanned activity is carried out, the external irradiating disinfection mode or the mixed disinfection mode can be automatically switched. The prediction of long-time unattended activities, basic unattended activities and frequent attended activities can be judged by a program according to the characteristics of places and by taking time as a main criterion and specifically combining the actual monitoring of a human body sensor or a similar monitoring device.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments, or make equivalent substitutions and improvements to part of the technical features of the foregoing embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
